I am a terrible liar. I came across another dataset I had to use, and this is the result. Still experimental, as I made these to teach myself the basics of fine-tuning, with notes extensively borrowed from https://huggingface.co/nothingiisreal/MN-12B-Celeste-V1.9
It is an RP finetune using 10,801 human-generated conversations of varying lengths from a variety of sources and curated by me, trained in ChatML format.
The big differences from Celeste is a different LoRA scaling factor. Celeste uses 8; I did several tests with this data before concluding I got lower training loss with 2.
Training took around 5 hours on a single Colab A100 (but I didn't do an eval loop). Neat that I could get it all to fit into 40GB of vRAM thanks to Unsloth.
It was trained with the following settings:
==((====))== Unsloth - 2x faster free finetuning | Num GPUs = 1

This mistral model was trained 2x faster with Unsloth and Huggingface's TRL library.
